Replacing Flickr?

So Flickr has launched a new redesign, and it’s crowded, jumbled and slow. Now on Flickr with its overlays, its fade-ins and loads, it’s unmoving side and top bars, Flickr’s design takes center stage, elbowing aside the photos that I’m there to see.

So I’m looking for a new community site where the photo I upload is the photo they display without overlays and with enough whitespace that people can consider it as a photograph. I’d like a site where I can talk with other photographers and get feedback, and where they’re happy to let me pay for multiple accounts for the various and separate ways I want to present my work.

500px looks like an interesting possibility, but they seem really heavy on the gamification, showing you “affection”, views, likes, favorites, on every photographer. Also, while their ToS are relatively easy to read, ToS;DR gives them a D.

What else should I be looking at?

A Quintet of Facebook Privacy Stories

It’s common to hear that Facebook use means that privacy is over, or no longer matters. I think that perception is deeply wrong. It’s based in the superficial notion that people making different or perhaps surprising privacy tradeoffs are never aware of what they’re doing, or that they have no regrets.

Some recent stories that I think come together to tell a meta-story of privacy:

  • Steven Levy tweeted: “What surprised me most in my Zuck interview: he says the thing most on rise is ‘sharing with smaller groups.'” (Tweet edited from 140-speak). I think that sharing with smaller groups is a pretty clear expression that privacy matters to Facebook users, and that as Facebook becomes more a part of people’s lives, the way they use it will continue to mature. For example, it turns out:
  • 71% of Facebook Users Engage in ‘Self-Censorship’” did a study of people typing into the Facebook status box, and not hitting post. In part this may be because people are ‘internalizing the policeman’ that Facebook imposes:
  • Facebook’s Online Speech Rules Keep Users On A Tight Leash.” This isn’t directly a privacy story, but one important facet of privacy is our ability to explore unpopular ideas. If our ability to do so in the forum in which people talk to each other is inhibited by private contract and opaque rules, then our ability to explore and grow in the privacy which Facebook affords to conversations is inhibited.
  • Om Malik: “Why Facebook Home bothers me: It destroys any notion of privacy” An interesting perspective, but Facebook users still care about privacy, but will have trouble articulating how or taking action to preserve the values of privacy they care about.

The Psychology of Password Managers

As I think more about the way people are likely to use a password manager, I think there’s real problems with the way master passwords are set up. As I write this, I’m deeply aware that I’m risking going into a space of “it’s logical that” without proper evidence.

Let’s start from the way most people will likely come to a password manager. They’ll be in an exploratory mood, and while they may select a good password, they may also select a simple one that’s easy to remember. That password, initially, will not be protecting very much, and so people may be tempted to pick one that’s ‘appropriate’ for what’s being protected.

Over time, the danger is that they will not think to update that password and improve it, but their trust in the password manager will increase. As their trust increases, the number of passwords that they’re protecting with a weak master password may also increase.

Now we get to changing the master password. Assuming that people can find it, how often will someone wake up and say “hey, I should change my master password?” Changing a master password is also scary. Now that I’ve accumulated hundreds of passwords, what happens if I forget my new password? (As it turns out, 1Password makes weekly backups of my password file, but I wasn’t aware of that. Also, what happens to the old files if I change my master password? Am I now exposed for both? That’s ok in the case that I’m changing out of caution, less ok if I’m changing because I think my master was exposed.)

Perhaps there’s room for two features here: first, that on password change, people could choose to have either master password unlock things. (Encrypt the master key with keys derived from both the old & new masters. This is no less secure than having backups available, and may address a key element of psychological acceptability.) You’d have to communicate that this will work, and let people choose. User testing that text would be fascinating.

A second feature might be to let people know how long they’ve been using the same master password, and gently encourage them to change it. This one is tricky mostly because I have no idea if it’s a good idea. Should you pick one super-strong master and use it for decades? Is there value to changing it now and again? Where could we seek evidence with which to test our instincts? What happens to long term memory as people age? Does muscle memory cause people to revert their passwords? (I know I’ve done it.) We could use a pattern like the gold bar to unobtrusively prompt.

A last element that might improve the way people use master passwords would be better browser integration. Having just gone to check, I was surprised how many sites my browser is tracking. Almost all of them were low value, and all of them now are. But why do we have two places that can store this, especially when one is less secure than the other. A browser API that allows a password manager to say “I’ve got this one” would be a welcome improvement.

Studying these ideas and seeing which ones are invalidated by data gathering would be cool. Talking to people about how they use their password managers would also be interesting work. As Bonneau has show, the quest to replace passwords is going to be arduous. Learning how to better live with what we have seems useful.

1Password & Hashcat

The folks at Hashcat have some interesting observations about 1Password. The folks at 1Password have a response, and I think there’s all sorts of fascinating lessons here.

The crypto conversations are interesting, but at the end of the day, a lot of security is unavoidably contributed by the master password strength. I’d like to offer up a simple contribution. Agilebits should make two non-cryptographic changes in addition to any crypto changes.

These relate to the human end of the issue, and how real humans make decisions. That is, picking a master password is a one time event, and even if there’s a strength meter, factors of memorability, typability, etc all come into play when the user selects a password when first installing 1Password.

Those human factors are not good for security, but I think they’re addressable.

First, the master password entry screens should display the same password strength meter that’s displayed everywhere else. It’s all well and good to discuss in a blog post that people need strong master passwords, but the software should give regular feedback about the strength of that master password. Displaying a strength meter each time it’s entered creates some small risk of information disclosure via shoulder-surfing, and adds pressure to make it stronger.

Second, they should make it easier to change the master password. I looked around, couldn’t figure out how to do so in a few minutes. [Update: It’s in preferences, security. I thought I’d looked there, may have missed it.]

1password

If master passwords are so important, then it’s important for the software to help its customers get them right.

There’s an interesting link here to “Why Johnny Can’t Encrypt.” In that 1999 paper, Whitten and Tygar made the point that all the great crypto in PGP couldn’t protect its users if they didn’t make the right decisions, and making those decisions is hard.

In this case, the security of password vaults depends not only on the crypto, but also on the user interface. Figuring out the mental models that people have around password storage tools, and how the interface choices those tools make develop those mental models is an important area, and deserves lots of careful attention.

I swear, I’m just looking at the articles!

Apparently, Playboy (possibly NSFW) has an app on iTunes. However, to get an app through the censors prudes “appropriate content” editors, there’s none of Playboy’s trademark nudes.

The Playboy app on ITunes

There hasn’t been such good news for their writers since the braille edition.

I’ll leave the jokes to you.

It’s worth thinking about this as the sanitized future if companies like Apple get to decide what we read or look at on the devices we buy.

Gamifying Driving

P90115441 highRes 640x419

…the new points system rates the driver’s ability to pilot the MINI with a sporty yet steady hand. Praise is given to particularly sprightly sprints, precise gear changes, controlled braking, smooth cornering and U-turns executed at well-judged speeds. For example, the system awards maximum Experience Points for upshifts carried out within the ideal rev range and in less than 1.2 seconds. Super-slick gear changes prompt a “Perfect change up” message on the on-board monitor, while a “Breathtaking U-turn” and a masterful touch with the anchors (“Well-balanced braking”) are similarly recognised with top marks and positive, MINI-style feedback.

For more, see “MINI Connected Adds Driving Excitement Analyser.”

Now, driving is the most dangerous thing most of us do on a regular basis. Most Americans don’t get any supplemental driving instruction after they turn 17. So maybe there’s actually something to be said for a system that incents people to drive better.

I can’t see any possible issues with a game pushing people towards things that are undesirable in the real world. I mean, I’m sure that before suggesting a U-turn, the game will use the car’s adaptive cruise control radar to see what’s around, even if the car doesn’t have one.

Privacy, Facebook and Fatigue

Facebook’s new Graph search is a fascinating product, and I want to use it. (In fact, I wanted to use it way back when I wrote about “Single Serving Friend” in 2005.)

Facebook’s Graph Search will incent Facebook users to “dress” themselves in better meta-data, so as to be properly represented in all those new structured results. People will start to update their profiles with more dates, photo tags, relationship statuses, and, and, and…you get the picture. No one wants to be left out of a consideration set, after all. (“Facebook is no longer flat“, John Battelle)

But privacy rears its predictable head, not just in the advocacy world:

Independent studies suggest that Facebook users are becoming more careful about how much they reveal online, especially since educators and employers typically scour Facebook profiles.

A Northwestern University survey of 500 young adults in the summer of 2012 found that the majority avoided posting status updates because they were concerned about who would see them. The study also found that many had deleted or blocked contacts from seeing their profiles and nearly two-thirds had untagged themselves from a photo, post or check-in. (“Search Option From Facebook Is a Privacy Test“, NYTimes)

Perhaps a small set of people will, as Batelle suggests, slow down their use of ironic, silly, or outraged likes, but the fundamental problem is that such uses are situated in a context, and when those contexts overlap, their meanings are harder to tease out with algorithms. People engage with systems like Yelp or LinkedIn in a much more constrained way, and in that constraint, make a much simpler set of meanings. But even in those simple meanings, ‘the street finds its own uses for things.’ For example, I get the idea that this 5-star review may be about something more than the design on a shirt.

There’s another study on “Facebook Fatigue:”

Bored or annoyed by Facebook? You’re not alone. A majority of people surveyed by the Pew Internet and American Life Project said they had taken sabbaticals from the social network at some point, to escape the drama, or the tedium. (“Study: Facebook fatigue — it’s real“, Jennifer Van Grove, CNet)

When our nuanced and evolved social systems are overlaid with technology, it’s intensely challenging to get the balance of technology and social right. I think the Pew research shows that Facebook has its work cut out for it.

Should I advertise on Twitter?

Apparently Twitter sent me some credits to use in their advertising program. Now, I really don’t like Twitter’s promoted tweets — I’d prefer to be the customer rather than the product. (That is, I’d like to be able to give Twitter money for an ad-free experience.)

At the same time, I’m curious to see how the advertising system works. I’d like to understand it and blog about it, but Twitter would like to maintain confidentiality around the program. They’re engaged in white-hot competition with Facebook and Google to be the new advertising platform of the future. At the same time, it’s less transparency than the exceptionally high bar that Twitter has generally aspired to.

That said with the launch of Control-Alt-Hack, my collaborators have stuff to sell and give away. (Not to mention maybe a sales bump for The New School of Information Security?) Or maybe I could promote other books that I think people should read, like “Thinking, Fast and Slow“). Does the nature of what I’m advertising change the calculus? Would advertising the giveaway make it different?

Then again, I do lots of “advertising” on Twitter already–I advertise the book, the game, blog posts, ideas I like. Does paying to bring them to more people dramatically change the equation?

Interestingly (and I think this is something that can be discussed, because it’s visible), I’m offered the chance to promote both tweets and myself.

I’d be really interested in hearing from readers about how I should take advantage of this, and if I should take advantage of it at all.

Lessons from Facebook’s Stock Slide

So as Facebook continues to trade at a little over half of their market capitalization of 3 months ago, I think we can learn a few very interesting things. My goal here is not to pick on Facebook, but rather to see what we can take away and perhaps apply elsewhere. I think there are three key lessons that we can take away:

  • The Privacy Invasion Gnomes are Wrong
  • Intent Beats Identity
  • Maximizing your IPO returns may be a short term strategy

Let me start with the “Privacy Invasion Gonmes.” The short form of their strategy is:

  1. Gather lots of data on people
  2. ???
  3. Profit

This is, of course, a refinement of the original Gnome Strategy. But what Facebook shows us is:

The Privacy Invasion Gnomes are Wrong

Gathering lots of data on people is a popular business strategy. It underlies a lot of the advertising that powers breathless reporting on the latest philosophical treatise by Kim Kardashian or Paris Hilton.

But what Facebook shows us is that just gathering data on people is actually insufficient as a business strategy, because knowing that someone is a a Democrat or Republican just isn’t that valuable. It’s hard to capitalize on knowing that a user is Catholic or Mormon or Sikh. There’s a limit to how much money you make being able to identify gays who are still in the closet.

All of which means that the security industry’s love affair with “identity” is overblown. In fact, I’m going to argue that intent beats identity every time you can get it, and you can get it if you…keep your eye on the ball.

Intent beats Identity

The idea that if you know someone, you can sell them what they need is a powerful and intuitive one. We all love the place where everyone knows your name. The hope that you can translate it into an algorithm to make it scale is an easy hope to develop.

But many of the businesses that are raking in money hand-over foot on the internet aren’t doing that. Rather, they’re focused on what you want right now. Google is all about that search box. And they turn your intent, as revealed by your search, into ads that are relevant.

Sure, there’s some history now, but fundamentally, there’s a set of searches (like “asbestos” and “car insurance”) that are like kittens thrown to rabid wolves. And each of those wolves will pay to get you an ad. Similarly, Amazon may or may not care who you are when they get you to buy things. Your search is about as direct a statement of intent as it gets.

Let me put it another way:
Internet company revunue per user

The graph is from Seeking Alpha’s post, “Facebook: This Is The Bet You Are Making.”

So let me point out that two of these companies, Facebook and LinkedIn, have great, self-reinforcing identity models. Both use social pressure to drive self-representation on the site to match self-representation in various social situations. That’s pretty close to the definition of identity. (In any event, it’s a lot closer than anyone who talks about “identity issuance” can get.) And both make about 1/9th of what Google does on intent.

Generally in security, we use identification because it’s easier than intent, but what counts is intent. If a fraudster is logging into Alice’s account, and not moving money, security doesn’t notice or care (leaving privacy aside). If Alice’s husband Bob logs in as Alice, that’s a failure of identity. Security may or may not care. If things are all lovey-dovey, it may be fine, but if Bob is planning a divorce, or paying off his mistress, then it’s a problem. Intent beats identity.

Maximizing your IPO returns may be a short term strategy

The final lesson is from Don Dodge, “How Facebook maximized the IPO proceeds, but botched the process.” His argument is a lot stronger than the finger-pointing in “The Man Behind Facebook’s I.P.O. Debacle“. I don’t have a lot to add to Don’s point, which he makes in detail, so you should go read his piece. The very short form is that by pricing as high as they did, they made money (oodles of it) on the IPO, and that was a pretty short-term strategy.

Now, if Facebook found a good way to get intent-centered, and started making money on that, botching the IPO process would matter a lot less. But that’s not what they’re doing. The latest silliness is using your mobile number and email to help merchants stalk find you on the site. That program represents a triumph of identity thinking over intent thinking. People give their mobile numbers to Facebook to help secure their account. Facebook then violates that intent to use the data for marketing.

So, I think that’s what we can learn from the Facebook stock slide. There may well be other lessons in an event this big, and I’d love to hear your thoughts on what they might be.
